A new lignan 1‐hydroxy‐2‐(4‐hydroxy‐3‐methoxyphenyl)‐6‐(3‐acetyl‐4‐hydroxy‐5‐methoxyphenyl)‐3,7‐dioxabicyclo[3.3.0]octane, the secoiridoid 2H‐pyran‐4‐acetic acid,3‐hydroxymethyl‐2,3‐dihydro‐5‐(methoxycarbonyl)‐2‐methyl‐, methyl ester, the phenylglycoside 4‐[ β ‐ d ‐xylopyranosyl‐(1→6)]‐ β ‐ d ‐glucopyranosyl‐1,4‐dihydroxy‐2‐methoxybenzene and the lactone 3‐[1‐(hydroxymethyl)‐1‐propenyl] δ ‐glutarolactone were isolated and identied on the basis of spectroscopic data including two‐dimensional NMR, as components of olive oil mill waste‐waters. The known aromatic compounds catechol, 4‐hydroxybenzoic acid, protocatechuic acid, vanillic acid, 4‐hydroxy‐3,5‐dimethoxybenzoic acid, 4‐hydroxyphenylacetic acid, 3,4‐dihydroxyphenylacetic acid, tyrosol, hydroxytyrosol, 2‐(4‐hydroxy‐3‐methoxy)phenylethanol, 2‐(3,4‐dihydroxy)phenyl‐1,2‐ethandiol, p ‐coumaric acid, caffeic acid, ferulic acid, sinapic acid, 1‐ O ‐[2‐(3,4‐dihydroxy)phenylethyl]‐(3,4‐dihydroxy)phenyl‐1,2‐ethandiol, 1‐ O ‐[2‐(4‐hydroxy)phenylethyl]‐(3,4‐dihydroxy)phenyl‐1,2‐ethandiol, d (+)‐ erythro ‐1‐(4‐hydroxy‐3‐methoxy)‐phenyl‐1,2,3‐propantriol, p ‐hydroxyphenethyl‐ β ‐ d ‐glucopyranoside, 2(3,4‐dihydroxyphenyl)ethanol 3 β ‐ d ‐glucopyranoside, and 2(3,4‐dihydroxyphenyl)ethanol 4 β ‐ d ‐glucopyranoside were also conrmed as constituents of the waste‐waters.
